The Science

Why fast charging slows down

Lithium-ion cells can drink hundreds of kilowatts when nearly empty — and only a trickle when nearly full. The battery management system tapers power to keep the cells cool and long-lived.

Plain English

Charging speeds explained

  • Level 1 — 2 kW

    ≈ 3 mi/hr

    A standard wall socket. Slowest possible. Fine for plug-in hybrids; an EV would need a day or two to fill from empty. Useful as a backup.

  • Level 2 — 7–22 kW

    ≈ 25–80 mi/hr

    Home wallbox or public destination charger. The everyday default. A typical EV fills overnight — and that’s the secret of EV ownership.

  • Rapid DC — 50–150 kW

    ≈ 30–60 min to 80%

    Motorway services. A coffee, a sandwich, and you’re back on the road. Most modern EVs hit 150 kW+ comfortably.

  • Ultra-rapid — 250–350 kW

    ≈ 18–25 min to 80%

    Tesla Supercharger V3/V4, Ionity, Electrify America. Limited by the car as much as the cable — very few EVs can drink the full 350 kW.

How we calculate

The formula, in the open

Charging time is energy needed divided by effective power. We use the same model whether the charger is 2.3 kW in your kitchen or 350 kW on a motorway forecourt.

time_hours = (battery_kWh × (target_pct − current_pct) ÷ 100) ÷ effective_kW

AC charging (home / destination)

effective_kW = min(charger_kW, ev_AC_max_kW) × 0.9 — the 0.9 factor accounts for losses in the charger and the car’s onboard rectifier.

DC fast charging

DC charging is piecewise. Below 80% state of charge, real cars average about 85% of their peak rated power once ramp-up is included. Above 80% the battery management system tapers aggressively to protect the cells, averaging roughly 30% of peak.

  • 0–80%: effective_kW = min(charger_kW, ev_DC_max_kW) × 0.85
  • 80–100%: effective_kW = min(charger_kW, ev_DC_max_kW) × 0.30

Real-world variation comes from battery temperature, state of health, charger backend, and whether the car is preconditioned. We model the typical, warm, healthy case.

Common Questions

Frequently asked

How long does it take to fully charge an electric car?

On a 7 kW home wallbox a typical 75 kWh EV takes about 11 hours from empty. On a 150 kW DC fast charger the same car reaches 80% in roughly 30 minutes. Plug it in overnight and the question stops mattering.

Why does charging slow down after 80%?

To protect lithium-ion cells from heat and chemical degradation, the battery management system tapers charging power as the cells fill. Power can drop to a quarter of peak between 80% and 100%, which is why EV trip planning targets 10–80% on the road.

What is the difference between AC and DC charging?

AC charging uses your car’s onboard charger to convert household alternating current to DC for the battery; this caps speed at 7–22 kW for most cars. DC fast charging bypasses the onboard charger entirely and feeds DC straight to the battery at 50–350 kW.

Does cold weather affect charging time?

Yes. A cold battery accepts less power because lithium ions move more sluggishly. Most modern EVs precondition the pack en route to a fast charger, warming the cells to restore full speed by the time you plug in.

Is it bad to charge an EV to 100%?

For day-to-day driving most manufacturers recommend an 80% ceiling on lithium-ion (NCM/NCA) chemistries, and 100% on LFP. Charge to 100% before a long trip and use the full range that day rather than letting it sit at 100% for weeks.

Can I use this calculator offline?

Yes — once the page has loaded, all calculations happen in your browser. There is also a simple JSON API at /api/charging-time for developers and AI tools.

Where do the EV specs come from?

Manufacturer technical specifications, cross-referenced with independent charging-curve measurements. See the methodology section above for sources and the formula in the open.

How accurate is the answer?

Within roughly ±10% for a warm, healthy battery on a working charger. Cold packs, busy charger sites, and degraded batteries can extend times. We model the typical good-conditions case so the number is honest, not optimistic.
